Eternexa exists to do one thing well: give you an exact, honest answer to a real money question — and then get out of your way. No motivational filler, no dark patterns, no sign-up. Just tools that work.
What we build
A growing library of financial calculators made for salaried Indians — take-home salary, income tax (old vs new regime), SIP, EMI, and more on the way. The same calculators power our free Android app and this website, so the numbers are consistent everywhere.
Private by design
On this website, every calculation runs inside your browser. The salary, loan and investment figures you type are never sent to us or stored on a server — they stay on your device. We do not ask you to sign up, and we do not want your personal data. See our privacy policy for the full details.
Accuracy is sacred
Tax and finance rules change every year. We track the Union Budget and update our figures for the current financial year (FY 2026-27), cross-checking against official sources. If you ever spot something that looks off, tell us at eternexa@gmail.com.
Official information sources
The government-related figures in our calculators are based on publicly available information published by:
- Income Tax Department, Government of India — incometax.gov.in
- Employees' Provident Fund Organisation (EPFO) — epfindia.gov.in
How we keep it free
Eternexa is supported by unobtrusive, clearly labelled advertising. That keeps every calculator free for everyone, forever, with no premium tier.
